Ivalve yokunciphisa uxinzelelo ibhekisa kwivalve enciphisa uxinzelelo lokungena kuxinzelelo lokuphuma olufunekayo ngokucinezela idiski yevalve, kwaye inokusebenzisa amandla ombindi ngokwawo ukugcina uxinzelelo lokuphuma lungatshintshanga xa uxinzelelo lokungena kunye nesantya sokuhamba sitshintsha.
Ngokuxhomekeke kuhlobo lwe-valve, ukunyanzeliswa kwe-outlet kunqunywe ngummiselo wokulawula uxinzelelo kwi-valve okanye ngenzwa yangaphandle. Iivalve zokunciphisa uxinzelelo zisetyenziswa ngokuqhelekileyo kwiindawo zokuhlala, zorhwebo, iziko kunye nezoshishino.
Uxinzelelo lokunciphisa ivalve yokuhlola-imbonakalo yeemfuno zokuhlolwa komgangatho
Ukuhlolwa komgangatho womphezulu wevalve yoxinzelelo
Ivalve yokunciphisa uxinzelelo akufanele ibe neziphene ezifana nokuqhekeka, ukuvala okubandayo, i-blisters, i-pores, imingxuma ye-slag, i-shrinkage porosity kunye ne-oxidation slag inclusions. Ukuhlolwa komgangatho womphezulu wevalvu ikakhulu ubandakanya uhlolo lweglosi yomphezulu, ukuthe tyaba, ukugqabhuka, imikrwelo, umaleko weoxide, njl. njl. Kufuneka kuqhutywe kwindawo ekhanyiswe kakuhle kwaye kusetyenziswa.
izixhobo zokuhlola umgangatho wobuchwephesha.
Umphezulu ongengoomatshini wevalve yokunciphisa uxinzelelo kufuneka ube mpuluswa kwaye ucaba, kwaye uphawu lokuphosa kufuneka lucace. Emva kokucoca, ukugalela kunye nokunyuka kufuneka kuhlanjululwe kunye nomphezulu wokuphosa.
Ubungakanani bevalve yokunciphisa uxinzelelo kunye nokuhlolwa kobunzima
Ubungakanani bevalve bunefuthe elithe ngqo ekusebenzeni kokuvula nokuvala kunye nokusebenza kokutywinwa. Ngoko ke, ngexesha lokuhlola ukubonakala kwe-valve, ubukhulu be-valve kufuneka buhlolwe ngokungqongqo. Ukuhlolwa komgangatho wevalve ikakhulu kubandakanya ukuhlolwa kwedayamitha yevalvu, ubude, ubude, ububanzi, njl. njl.
Uvavanyo lokumakisha ivalve yokunciphisa uxinzelelo
Ukuhlolwa kwenkangeleko yevalve yokunciphisa uxinzelelo kufuna ukuhlolwa kwelogo yevalve, ekufuneka ihlangabezane neemfuno zemigangatho yemveliso yevalvu. I-logo kufuneka icace kwaye ingabi lula ukuwa. Jonga ilogo yevalve yokunciphisa uxinzelelo. Umzimba wevalvu kufuneka ube nesixhobo somzimba wevalvu, uxinzelelo lwegama, ubungakanani begama, inombolo yesithando somlilo esinyibilikayo, indlela yokuhamba, kunye nophawu lokuthengisa; I-nameplate kufuneka ibe nemidiya esebenzayo, uluhlu loxinzelelo lokungena, uluhlu loxinzelelo lokuphuma, kunye negama lomenzi. Iimpawu zemodeli, umhla wokwenziwa.
Uxinzelelo lokunciphisa ibhokisi yevalve ileyibhile yebhokisi yokuhlola ukupakishwa kombala
Iivalvu zokunciphisa uxinzelelo kufuneka zipakishwe ngaphambi kokuba zishiye umzi-mveliso ukukhusela iivalvu emonakalweni ngexesha lokuthuthwa nokugcinwa. Ukuhlolwa kwembonakalo yevalve yokunciphisa uxinzelelo kufuna ukuhlolwa kweleyibhile yebhokisi yevalve kunye nokupakishwa kwebhokisi yombala.
Uxinzelelo lokunciphisa ivalve yokuhlolwa kweemfuno zokuhlola ukusebenza
Uxinzelelo lokunciphisa uxinzelelo lwevalvu elawula ukuhlolwa kokusebenza
Ngaphakathi koluhlu lolawulo loxinzelelo olunikiweyo, uxinzelelo lwe-outlet kufuneka luhlengahlengiswe ngokuqhubekayo phakathi kwexabiso eliphezulu kunye nexabiso elincinci, kwaye akufanele kubekho ukuphazamiseka okanye ukungcangcazela okungaqhelekanga.
Ukuhlolwa kweempawu zokuhamba kwevalve ngoxinzelelo
Xa i-outlet flow flow itshintsha, i-valve yokunciphisa uxinzelelo akufanele ibe nezenzo ezingaqhelekanga, kunye nexabiso eliphambukayo elibi loxinzelelo lwalo lokuphuma: kwi-valve yokunciphisa uxinzelelo oluthe ngqo, ayiyi kuba ngaphezu kwe-20% yoxinzelelo lokuphuma; kwiivalvu zokunciphisa uxinzelelo oluqhutywa ngumqhubi, akuyi kuba nkulu kune-10% yoxinzelelo lokuphuma.
Ukuhlolwa kweempawu zoxinzelelo lwevalve yokunciphisa uxinzelelo
Xa uxinzelelo lokungena lutshintsha, ivalve yokunciphisa uxinzelelo kufuneka ingabi nokungcangcazela okungaqhelekanga. Ixabiso layo lokuphambuka koxinzelelo lwe-outlet: kwi-valve yokunciphisa uxinzelelo olusebenza ngokuthe ngqo, ayiyi kuba ngaphezu kwe-10% yoxinzelelo lokuphuma; kwiivalvu zokunciphisa uxinzelelo oluqhutywa ngumqhubi, akuyi kuba nkulu kune-5% yoxinzelelo lokuphuma.
| Ubungakanani bomsebenzi DN | Ubuninzi bokuvuza umthamo wehla (amaqamza)/min |
| ≤50 | 5 |
| 65~125 | 12 |
| ≥150 | 20 |
Ukunyuka kwe-elastic seal ye-outlet pressure gauge kufuneka ibe yintsimbi ye-zero - isitywina sentsimbi akufanele sidlule i-0.2MPa / min.
ukusebenza ngokuqhubekayo
Emva kweemvavanyo eziqhubekayo zokusebenza, isenokuhlangabezana nokusebenza kolawulo loxinzelelo kunye neemfuno zokuhamba.
